COMSOL® Analysis-Led Design of Prototype Coil Program for Bi-2212 Coils

E. Bosque [1], U. Trociewitz [1],
[1] Applied Superconductivity Center - National High Magnetic Field Laboratory, Tallahassee, FL, USA

The National High Magnetic Field Laboratory (NHMFL) strives to push magnet technology to ever higher field strengths. Supported by a unified effort of material research as well as coil research, Bi2Sr2CaCu2O8+δ (Bi 2212) technology shows promise as a high temperature superconductor (HTS) ... Read More

COMSOL Multiphysics® as a Tool for Biomedical Engineering Students to Harness Physical Processes

J. Bush [1],
[1] Old Dominion University, Norfolk, VA, USA

The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... Read More

Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corp., Hauppauge, NY, USA

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... Read More

Analysis of D-Shaped Toroidal Superconductive Coils for Medium Size Fusion Experiment Facility

V. Cocilovo [1],
[1] ENEA Frascati Research Center, Frascati, Italy

The research in magnetic confinement fusion is carried out through electromagnetic machines, with a toroidal geometry, where a hot plasma of heavy hydrogen isotopes (deuterium and tritium) is contained in a vacuum vessel. Due to the very high temperatures reached by the plasma, strong ... Read More

Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting

L. Howard [1], D. Tafone [2], D. Grbovic [1], A. Pollman [1],
[1] Naval Postgraduate School, Monterey, CA, USA
[2] Ramapo College of New Jersey, Mahwah, NJ, USA

Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... Read More

Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... Read More

Simulator for the Development of Electromagnetic Heart Assist Devices

D. G. Hurd [1],
[1] Iowa State University, Ames, IA, USA

Every year, in the United States alone, more than 40,000 infants are born with congenital heart defects (CHD) and an additional 550,000 adults are diagnosed with heart failure. Every year, $110 billion is spent on treating heart attacks and $20-39 billion on heart failure in the US. The ... Read More

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

S. Baidya [1], A. M. Hassan [1], B. A. Pazmiño Betancourt [2], J. F. Douglas [2], E. J. Garboczi [3],
[1] Computer Science Electrical Engineering Department, University of Missouri - Kansas City, Kansas City, MO, USA
[2] Materials Science and Engineering Division, National Institute of Standards and Technology, Gaithersburg, MD, USA
[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... Read More

Improving Thermal Effect on Biological Tissue using Multiphysics Simulation and Shape Optimization

A. Ward [1],
[1] System Insight Engineering, Centennial, CO, USA

As minimally invasive and robotic surgical devices get smaller, designing precise energy delivery to create the desired tissue effect becomes a key component in product development. With many interdependent physical phenomena occurring simultaneously, it becomes necessary to use tools ... Read More
